Investigation on Impacts of Industrial Fluoride-induced Pollution on Environment and Residents' Health / 环境与健康杂志

ABSTRACT

ve To understand the impacts of industrial fluoride-induced pollution on environment and human health. Methods The contents of fluorides in environmental media, such as air, soil, vegetables, weeds, branches and leaves in area around a certain chemical factory (polluted area) were monitored. The prevalance of dental fluorosis, the contents of fluorides in hair and nail were investigated among 87 individuals without history of exposure to industrial fluorides, living in polluted area for more than 5 years, and 132 individuals in control area. Results Higher fluoride levels in environmental medias, higher prevalance rates of dental fluorosis, high contents of fluorides in hair and nails of population were found in polluted area compared with those in control area. Conclusion The in-dustrial fluoride-induced pollution from this chemical factory had resulted in the hazardous impacts on environmental quality and human health.
